A few weeks ago, the Team Twiizers released the Twilight hack source code, the bug in the savegame data file in the Zelda Twilight Princess game that enabled the installation of the Homebrew Channel on every Wii out there, and, until last month, was the only way to run homebrew.
Releasing the source was a good idea?
Absolutely! Here is another bug found in Super Smash Bros. Melee, from the same team behind the BannerBomb exploit.
Here is the video:
The exploit will be released shortly, and it should be impossible to patch for Nintendo, as it is a bug in the level editor, and not in the savegame data. (The way of fighting the Twilight Hack for Nintendo is automatically delete it from the internal memory... they did not correct anything... they cannot patch a game on-the-fly as in the PS3 or the Xbox360
For who is not willing to wait, is available the good Bannerbomb, better in my opinion, as is not required to have Super Smash Bros. Melee
